Here, the stimulus required to reinforce a particular behavior is termed the correct stimulus. When how a subject behaves is affected by a stimulus, then there is a degree of control, although it is not absolute. Russian physiologist Ivan Pavlov discovered that a neutral stimulus that has been repeatedly associated with a meaningful stimulus, will eventually have meaning too.

(For example, we need to pull over for emergency vehicles, even though they do not all look and sound exactly the same.) You ask the student, What are these? The student says, Fruit, even though they are all different fruits. In stimulus generalization stimuli similar to the training stimulus are effective. _____________ involves the behavioral principles of:Reinforcement and extinction.Reinforcement is provided for correct responses in the presence of the discriminative stimulus and extinction (withholding reinforcement) in the presence of the stimulus deltas.
